If your pregnancy is uncomplicated, it is safer to exercise than not. For example, women who exercise have less risk of gestational diabetes and high blood pressure, which are both risk factors for premature labour.
One study showed that women who had been active before pregnancy but stopped in their first trimester had longer labour times. They were also more likely to have medical assistance during labour than those who exercised throughout their pregnancy.
Staying active can also:
- help you sleep better
- reduce your chances of suffering from some common pregnancy symptoms, such as varicose veins, swollen feet and fatigue
- improve your mood and reduce your anxiety.
If you have a high risk of premature birth
Although exercise alone does not cause premature birth, it is possible that it could complicate an existing problem, such as a weak cervix.
Listen to your body and if something does not feel right, see to your midwife or GP.
